Hi, I'm Director Doug, and you know since I've been the director of Discovery Mountain,

I seem to hear sounds everywhere.

I guess it comes with the job.

I notice sounds when I'm at a restaurant, like the sound that a plate of hot fajita vegetables makes

when the server brings it to the table, and the sound of singing as a family celebrates a birthday. Speaking of birthdays, it sounds like it's Mrs. Lee's birthday in Discovery Mountain.

Let's listen, but here's a warning.

There's one sound that's part of her birthday celebration that's really annoying.

But it just might help Detective Lana solve another case.

Come on, let's take another mini-adventure in Discovery Mountain.

Would they, Mrs. Lee?

Oh, thank you, Lana.

Thank you, class.

I just love the balloons.

Oh, look.

Someone drew a picture of me on the chalkboard.

Very nice drawing.

Mrs. Lee, we all got your birthday card. Here, open it. Oh, thank you,

Erica. Thank you, class. You are one of the nicest groups of first and second graders that I've

ever taught. Nice, neat printing on the card envelope. Is that you're printing, Erica? Open the envelope.

Okay, let's see. It says, happy birthday teacher, and inside it says,

Happy Happy Birthday.

Well, what do you know?
